Tube - speaker matching

Interesting. I hope he has the clearance to publish Stereophyle's graphs.

Tubed amplifiers were traditionally matched with reactive speakers. The only resistive speaker I know of is the Magneplainers/Magnepans. That said, the high impedance at low frequency resonance is a good thing as the woofer is uncontrolled at that frequency. Other impedance peaks are going to be a frequency response "suck out" with tubed amps.

The key is finding a good, tube friendly speaker. I have Triangle Zerius speakers on 2A3 amps.
 
Good link! Very readable explanation of the relationship between capacitive phase angle plus impedance.
 
I drive Sansui SP1700 3way 12" 5spkr ported reflex speakers with my 9303 6bq5 PP Mag amp with great success and I know squat about all the freq. sucks and impedance fluctuatons and capacitive phase angles and uncontrolable woofers. Who can possibly have all that info on a speaker? All I know is they sound great, as do my JBL 88s 2way 12" ported reflex. Ive yet to hook em up to my Infinity Primus 362s but will. Even a tiny 0.75watt SE "Darling" amp was amazing on the sansui's.

This makes sense to me. Knowing numbers is no help as the source impedance is almost as complex as the speakers being driven.
